Description

  The present invention relates to a video projection management apparatus for projecting and controlling video projection onto a moving handrail of a man conveyor such as an escalator apparatus.

  In conventional escalator devices, in order to provide information such as advertisements to users, information such as characters, figures, patterns, etc. is directly entered on the surface of the moving handrail (handrail belt). The periphery was coated with a flexible resin (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 63-162777

However, once information such as advertisements using characters, figures, and patterns is entered on the moving handrail, the display of the advertisement information is coated with resin or the like, so that it cannot respond to immediate changes in content.
For example, in the case of an escalator installed in a department store, when it is necessary to change the contents of advertisements displayed on a moving handrail by changing the interior of the store, or when it is desired to enter event details such as a time sale on the moving handrail. The advertisement display corresponding to the situation change cannot be entered on the moving handrail.
Moreover, since the advertisement display content of the moving handrail cannot be displayed in a variety of ways, the amount of information is small, and the advertising effect on the escalator device user is diminished.

  The present invention has been made in order to solve the above-described problems. An image projector is used to project and display an advertisement on the surface of a moving handrail, and the content of the projection display is changed according to the situation at that time. It is an object of the present invention to obtain a video projection management device that can easily change and project and display a video with a large amount of information and a variety of changes on the surface of a moving handrail to enhance the advertising effect.

Similarly to the control unit 3a, the data conversion unit 3d includes a CPU, a RAM, and a ROM in which a control program is written, and can perform data transmission / reception and data processing. The selection unit 3b includes a RAM or a hard disk (HD) as the second memory 18b, and can write and retrieve data from the outside.
The recording unit 3c includes a RAM or a hard disk (HD) as the first memory 18a, and can write and retrieve data from the outside. The communication unit 3e is an interface that mediates exchange of data between the inside and the outside of the image processing apparatus 3.

Further, the control means 3a is electrically connected to the selection means 3b, the recording means 3c and the data conversion means 3d so that data can be transmitted / received to / from each means.
Further, the control means 3a is electrically connected to the escalator control panel 7 via the communication means 3e, for example, operation information such as the moving speed and travel direction of the step 13 of the escalator device 2, and the operation start of the escalator device 2. Signals and operation stop signals can be received.

The selection unit 3b and the recording unit 3c are electrically connected to the external terminal 4 via the communication unit 3e.
Furthermore, the data conversion means 3d is electrically connected to the video projectors 5a to 5f.
The video projectors 5a to 5f perform projection display on the moving handrail 15 based on the data written in the first memory 18a and the second memory 18b.

  Next, the arrangement state of the video projectors 5a to 5f will be described with reference to FIGS. In one video projector, since the video projection area is too wide, the video cannot be projected and displayed on the entire surface of the moving handrail 15. In order to project and display an image on the entire surface of the moving handrail 15, the traveling direction of the moving handrail 15 is such that the six image projectors 5a to 5f are connected to each other along the surface of the moving handrail 15. Are arranged in a row. As a result, the entire surface of the moving handrail 15 is covered as a video projection area of the video projectors 5a to 5f. For example, the video projector 5a and the lower floor side of the video projection area on the surface of the moving handrail 15 by the projection of the video projector 5a overlap with the upper floor side of the video projection area by the projection of the video projector 5b. 5b is arranged. Similarly, the lower floor side of the video projection area by the projection of any one of the video projectors 5b to 5e on the upper floor side overlaps the upper floor side of the projection area of the adjacent video projectors 5c to 5f on the lower floor side. The video projectors 5c to 5f are arranged so as to have

Next, data written to the first memory 18a and the second memory 18b will be described.
The data written in the first memory 18a is image base data 17 used for the projection display of the video projectors 5a to 5f. The image base data 17 is written into the first memory 18 a by the external terminal 4. For example, the data of the images A to D shown in (a) to (d) of FIG. 5 are written as the image base data 17 in the first memory 18 a.

The data written in the second memory 18b is selected image data 16a, video content data 16b, display setting data 16c, display method data 16d, and scroll speed data 16e, which are defined as management data.
The selected image data 16a controls which image base data 17 out of the plurality of image base data 17 written in the first memory 18a is projected and displayed on the surface of the moving handrail 15 from the video projectors 5a to 5f. This is data for instructing the means 3a. Then, video content data 16b, display setting data 16c, display method data 16d, and scroll speed data 16e are set for each selected image data 16a.

  The video content data 16b instructs the control means 3a how to use the image base data 17 specified by the selected image data 16a in combination. For example, the control means determines whether the individual image base data 17 written in the first memory 18a is used as it is, or the arrangement of a plurality of image base data 17 is used as an image group. This is data for instructing 3a. When used as an image group, the arrangement method is also written as data.

  The display setting data 16c instructs the control means 3a to project the image base data 17 designated by the selected image data 16a to which position on the surface of the moving handrail 15 and in what size. For example, the video projection position is a two-dimensional coordinate if the width direction of the moving handrail 15 is the X axis, the traveling direction of the moving handrail 15 is the Y axis, and one point of the image projection area viewed from above the moving handrail 15 is the origin. Can be represented. For example, the point P shown in FIG. 2 can be set as the coordinate origin.

The display method data 16d instructs the control means 3a when and how to project and display the image base data 17 designated by the selected image data 16a. For example, the control unit 3a is instructed to display repeatedly for 2 hours from 9 o'clock.
The scroll speed data 16e is for instructing the control means 3a in which direction and at what speed the image base data 17 designated by the selected image data 16a is scrolled.

Hereinafter, a specific example of the management data written in the second memory 18b will be described with reference to FIG.
In the selected image data 16a, the image A and the image B are single, and the image C and the image D are grouped and specified.
The image A illustrated in FIG. 5A is displayed in full size, scrolling in the Y direction at 10 m / min from 9:00 to 11:00, and repeatedly displayed, starting from the coordinates (0, 0). This is written in the second memory 18b as data for instructing the control means 3a. Here, the full size refers to the area of the entire surface of the moving handrail 15.

  In addition, the image B illustrated in FIG. 5B has a size of 50 mm in the Y direction and 50 mm in the X direction, starting from the coordinates (30, 0), and lapses in the Y direction from 9:00 to 11:00. It is written in the second memory 18b as data for instructing the control means 3a to repeatedly display so as to scroll with the speed fluctuation of the sine wave with time.

  Further, the images C and D shown in FIGS. 5C and 5D connected in the Y direction are grouped, and the coordinates (50, 1200) are set between 9:00 and 17:00. As a starting point, data is written in the second memory 18b as data for instructing the control means 3a to repeatedly display the image by scrolling in the -Y direction at a speed of 30 m / min at a size of 50 mm in the X direction and 300 mm in the Y direction. .

As described above, the management data designates the image base data 17 to be projected and displayed from the image base data 17 in order to project and display a desired video on the surface of the moving handrail 15 from the video projectors 5a to 5f. Or instructing the specified image base data 17 in what combination, when, in what position, in what size, in what direction, and at what speed, and in what direction to perform projection display. To do.
Since the image base data 17 written in the first memory 18a and the management data written in the second memory 18b are written from the external terminal 4 via the communication means 3e, the status of date / time, time zone, event, etc. In response to the change, it is possible to change the written contents promptly.

Next, data correction performed by the control means 3a will be described.
The image base data 17 written in the first memory 18a and the management data written in the second memory 18b are read by the control means 3a and stored in the third memory 18c. The read data is corrected by the control means 3a, as described below, in consideration of operation information data such as the traveling direction of the handrail 15 and projection specifications set for each of the video projectors 5a to 5f. The projection specification includes the distance between the surface of the moving handrail 15 and the image projectors 5a to 5f, the interval between the image projectors 5a to 5f, and the like, and projection specification data is written in the ROM of the control means 3a in advance. Yes.

  As described above, the video projection areas of the adjacent video projectors 5 a and 5 b overlap on the surface of the moving handrail 15. The image base data 17 is corrected by the control means 3a based on the management data, the operation information data, and the projection specification data so that the projected video is not displayed in the overlapped video projection area.

  For example, when it is desired to scroll the crab image in FIG. 5B along the Y direction of the moving handrail 15, the crab image is an image projection area covered by each of the adjacent image projectors 5a and 5b. The overlapping parts will move. The control means 3a performs correction according to the projection specification data of the video projectors 5a and 5b so that the crab seems to move continuously even in the area where the video projection areas overlap. The same data correction is performed for the other adjacent video projectors 5c to 5f.

Further, in accordance with the projection specification data of the video projectors 5a to 5f, correction for focusing the video on the projection display location is performed at the same time.
These corrections are individually corrected for each of the video projectors 5a to 5f and sent to the data conversion means 3d as individual correction data.

Next, data conversion performed by the data conversion means 3d will be described.
The data conversion means 3d converts the correction data individually corrected for each of the video projectors 5a to 5f into one data and transmits the data to the video projectors 5a to 5f. Although the data set for each of the video projectors 5a to 5f may be transmitted separately, the wiring between the video projectors 5a to 5f and the data conversion means 3d is established by communicating the data together. Simplified.

Next, control when the image projection management apparatus 1 configured and connected as described above projects and displays an image on the surface of the moving handrail 15 will be described based on the flowchart of FIG. In FIG. 4, steps 101 to 114 in the text are denoted as S101 to S114 for convenience.
The control means 3a checks the operation start signal of the escalator control panel 7 and determines whether or not the escalator device 2 is in operation. (Step 101).

In step 101, when the escalator device 2 is not in operation, the control means 3a repeats step 101 until it is determined that the escalator device 2 is in operation.
When the control means 3a determines in step 101 that the escalator device 2 is in operation, the control means 3a checks whether data is written in the first memory 18a and the second memory 18b. Perform (step 102).

When it is determined that the data in the first memory 18a and the second memory 18b are written, the control unit 3a proceeds to step 104. If no data is written in the second memory 18b and the first memory 18a, the control means 3a requests the external terminal 4 to write data, and the external terminal 4 sends the second memory 18b and the first memory 18a to the first memory 18b. Data is written to the memory 18a (step 103). When data is written in the first memory 18a and the second memory 18b, the process proceeds to step 104.
In step 104, the control means 3 a receives operation information data from the escalator control panel 7. Next, the control means 3a reads the data in the second memory 18b and the first memory 18a (step 105).

The control means 3a converts the data read from the first memory 18a and the second memory 18b into the operation information data of the escalator control panel 7 received in step 104 and the projection specifications set for each of the video projectors 5a to 5f. At the same time, the data is corrected, and the corrected data is transmitted to the data conversion means 3d (step 106).
In the data conversion means 3d, the correction data individually corrected for each of the video projectors 5a to 5f is converted into one data and transmitted to the video projectors 5a to 5f (step 107).
The image projectors 5a to 5f project and display an image based on the data received from the data conversion means 3d on the surface of the moving handrail 15 (step 108).

Next, the control means 3a checks the operation stop signal of the escalator control panel 7, and determines whether or not the escalator device 2 has stopped operating (step 109).
When the control means 3a determines in step 109 that the operation of the escalator device 2 has been stopped, the control means 3a transmits a video projection stop signal to the video projectors 5a to 5f, and the video projectors 5a to 5f move the moving handrail 15 The projection display is stopped (step 110).
If the control means 3a determines in step 109 that the operation of the escalator device 2 has not stopped, that is, if the control means 3a determines that the operation of the escalator device 2 continues, the control means 3a performs the current control. The operation of the image projection management device 1 is continued while maintaining (step 111).

Next, the control means 3a accesses the first memory 18a and the second memory 18b, and determines whether or not the data written in the first memory 18a and the second memory 18b by the external terminal 4 has been updated. Judgment is made (step 112).
If the data written in the first memory 18a and the second memory 18b has been updated, the process returns to step 105 and the operation of the video projection management apparatus 1 is continued. If the data has not been updated, the process proceeds to step 113.

Next, the control means 3a determines whether or not the operation information data of the escalator control panel 7 has been changed (step 113).
If the operation information data has not been updated, the process proceeds to the flow of step 109, and the subsequent operations of step 109 to step 113 are repeated.
If the operation information data has been updated, the control means 3a reads the operation information data on the escalator control panel 7 (step 114) and returns to step 106.

5 is written in the first memory 18a as the image base data 17 and the management data in FIG. 6 is written in the second memory 18b, respectively, according to the flow of steps 101 to 108 described above. Assume that an image is projected and displayed on the surface of the moving handrail 15. At 10:00, as shown in FIG. 7, the crab walks in the Y direction on the surface of the moving handrail 15 from the video projectors 5a to 5f, and the advertisement scrolls in the -Y direction on the sea. The image is projected and displayed as shown.
In this way, it is possible to project and display an image on the surface of the moving handrail 15 by arbitrarily setting the direction, speed and size of the projection display for each of the image base data 17 written in the first memory 18a. . Therefore, for the user of the escalator device 2, the amount of information is increased and a video with a great deal of change is provided, so that the advertising effect is improved.

  In the video projection management apparatus 1 of the present invention, the image base data 17 recorded in the first memory 18a is based on the management data in the second memory 18b and the projection specifications set for each of the video projectors 5a to 5f. Then, it is corrected and converted by the control means 3a and the data conversion means 3d. The converted data is transmitted to the video projectors 5a to 5f, and is projected and displayed on the surface of the moving handrail 15 from the video projectors 5a to 5f. Therefore, it is possible to project and display an image on the surface of the moving handrail 15 by arbitrarily setting the direction, speed and size of the projection display for each of the image base data 17 written in the first memory 18a. Therefore, for the user of the escalator device 2, the amount of information is increased and a video with a great deal of change is provided, so that the advertising effect is improved.

  In addition, since the data written in the first memory 18a and the second memory 18b is written from the external terminal 4 via the communication means 3e, the time, time zone, event, etc. The image can be changed correspondingly, and an image corresponding to the changed content can be projected and displayed on the surface of the moving handrail 15.

In the present invention, the escalator device 2 is used as the man conveyor. However, the escalator device 2 is not limited to the escalator device 2, and another man conveyor such as a moving sidewalk may be used.
The number of video projectors 5a to 5f is set to 6, but the number of video projectors 5a to 5f is not limited, and may be set as appropriate according to the length of the moving handrail 15 and the like.
